microcom 2023.09.0

Highlights of this release are:

• use flock(2) instead of POSIX locking
  This is easier to use today as /var/lock (or /run/lock) are not user-writable in modern systems. See commit 34e7fe5 for some more details.

• A new command sendescape to send a Ctrl-\. This makes it possible to drive a nested microcom instance.

• Several fixes here and there, e.g. consistently use LFS and improve on rfc2217 subnegotiation handling
